Same comments as above, but with quotes for context (and fewer smilies). Perhaps I misread the recipe or am missing the philosophy of ZK's atomicity. It wouldn't be the first time. To your points: 1) shouldn't you check to see if you already have a lock before you do the create? that will remove the code right after the create in the getLock() methods. We do the create to ensure that we, at some point, will hold a lock. I do want to do the create, ensuring my turn, and then wait until I'm at the front of the line (front being defined in the exclusive or shared way). 2) if you already have an exclusive lock, shouldn't that also count as a shared lock? There should be a unit test that ensure that this does indeed happen, semantically. Exclusive locks block all shared access, if I take your meaning correctly. 3) the error handling is a bit problematic. a connection loss exception or an interrupt can leave a process holding a lock without knowing it. I thought the API guaranteed that in the event of a connection loss the EPHEMERAL creation property would guarantee that when the session timed out the file would be removed and watchers would be signaled. 4) when you go through the children, you may end up checking for the existence of every znode before you, which could be wasteful. All but those behind me in the line of locks. This could certainly be optimized and is something I thought about, but moved past to get the rough implementation in flight. i think it may be better to expand the current locking code to handle shared lock rather than add a new lock implementation. the current lock recipe implementation only does exclusive locks, but it is implemented in a way that makes it easy to support shared locks as well and it takes care of the above problems. If the above 4 points hold, then extending the other implementation may be better for the community. I hope you'll include the code, but if not, we're very happy with it and appreciate ZooKeeper!

Sam Baskinger commented on ZOOKEEPER-767:
-
Thanks of the code-snippet Benjamin. You're absolutely right. Fixed #1.
Regarding #2, when getting a shared lock we ignore existing shared locks and
only look for exclusive locks. Line 225 of the new patch has:
{noformat}
if (child.startsWith(EXLOCK)) { ...
{noformat}
If I'm not confusing the matter, while a single exclusive lock node
represents a single exclusive lock, a series of contiguous shared lock nodes
make up the total of a shared lock. I took some time to stare at the code in
question and corresponding code in the getExclusiveLock() call and I think they
are as we intended them.
As for #3, wow, I fell asleep at the IDE for that one. Thank you. Any exception
will result in a roll back of the lock file creation and the Exception is
propagated up the stack.
Now, the larger question of the existing lock implementation, the existing
{{WriteLock.java}} doesn't appear to closely follow the recipe (I'm reading
http://hadoop.apache.org/zookeeper/docs/current/recipes.html#sc_recipes_Locks )
. What would prevent us from using it is the lack of first scheduling a lock
(creating the node) and then doing the blocking logic. We realize this is
potentially more work, but there may be some very high reader contention and we
need to ensure that a single writer process doesn't starve. There is the added
benefit of being able to observe the finite list of readers that must complete
before the writer can lock.
Other than that, if the existing WriteLock had shared/exclusive coexisting and
a block-until-timeout construct, we would probably prefer to spend our time
integrating that code than crafting up our own. It may well be that the
{{SharedExclusiveLock.java}} file has too many production concerns in it and
doesn't suite the goal of a recipe file.
